My mother blood group B and my father is A then my blood group is O HOW IS POSSIBLE?gayatri27 Thursday, April 10, 2014

actually there's no problem associated with ur blood type but since u are Rh[negative] there are instance/s that ur baby can acquiered Hemolytic disease of the newborn (erythroblastosis) if ur husband is Rh( positive)...there are 4 major blood type A, B ,O, and AB. in ur case, blood type O and B are compatible in ur blood type but we have to consider the other factors that some blood type even they are compatible each other, there are many risk behind it.NoarPol Thursday, July 12, 2012

Cross matching is never done by this method indeed you have to
1-add one drop of serum or plasma
of the patient with one drop of the donor either by MTS system or by tube Mthd.
2-Cheeck if there is any reaction if there is any you have to identify the antibodies at the surfece of the antigen of the RBC.
3. prepare 0.8 blood suspension from the blood of donor against the serum of the patient.
4.Use Mts system for screning of donor with serum of the patient SC1,SC2 against all panel antibodies which is 11 or 16 if there is any reaction with any of the antibodies.
5- do confirm which antibodies and do it again with the same just to confirm.
this all before trying to do any x matching still as you have life at your hand so you have to asure that you are doing the right thing .
6-Once you know the antibodies now you can do cross matching .

I DONATED BLOOD AT ONE BLOOD BANK THEY GIVE MY BLOOD GROUP AS O Rh POSITIVE. LATER I DONATED AT ANOTHER BLOOD BANK THEY GIVE MY BLOOD GROUP AS O Rh NEGATIVE IS IT POSSIBLE?NandkishorAher Wednesday, January 11, 2012

no big deal but at 28weeks of your pregnancy go for anti-D [RhoGAM], then at 34weeks somefew weeks before labour and lastly after delivery. if not ur child might suffer from hemolytic disease of the newborn(HDN), this can cause miscarriages, anaemia.Guest Tuesday, May 06, 2014
